Bests & Worsts Reviews from Amazon

I bought these on April 2nd, 2018 and returned them the next day. I wore them in my office all day with no issues. When I ant for a run, the left ear bud cut out about every ten seconds. It would reconnect, disconnect over and over. I went to the gym and they worked perfectly. Left the gym to run home and again the left ear bud cut out over and over. I guess if you plan to only wear them inside, they are great. Very disappointed.
